wmoow SHUTTER AND CURTAIN.

SPECIFICATION forming part of Letters Patent No.'506,537, dated October10, 1893. Application filed May 22 1893- Serial No. 475,044. (No model.)

To aZZ whom it may concern:

. Be it known that I, JOHN ODoNNELL, of Mountain Lake Park, in thecounty of Garrett and State of Maryland, have invented a new andImproved Window Shutter and Curtain, of which the following is a full,clear, and exact description.

My invention relates to improvements in window shutters and curtains orshades; and the object of my invention is to produce a very simple andcheap, but extremely strong and durable shutter and curtain, which isconstructed of open chain-like netting strong enough to resist anordinary bullet, and also to prevent burglars from gaining easy accessto a house; and a further object of my invention is to construct theshutter and shade in such a way that it may be easily fastened at anydesired height, will run up automatically when released, will serve thepurposes of an ordinary mosquito screen as well as a shade, and may beapplied to any ordinary window of a building, car, or other structure.

Another object of my invention is to construct the shade so that it willserve the above described purposes and will also afiord sufficientventilation in warm weather.

To these ends my invention consistsof certain features of constructionand combinations of parts, as will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar figures of reference indicatecorresponding parts in all the views.

Figure l is a sectional front elevation of a window provided with myimproved shutter and shade or curtain. Fig. 2 is a longitudinal orvertical section on the line 22 in Fig. 1. Fig. 3 is a sectional plan ofthe window frame and shutter or curtain. Fig. 4 is an enlarged detailView of a section of the shutter or curtain; and Fig. 5 isa detail viewof a modified means of raising the shutter or curtain.

The window frame is of the usual kind and may be of any ordinaryconstruction, and in it are hung the usual sliding sashes 11. Above thewindow frame is a supplemental or roller frame 12 in which is journaledthe roller 13, and this carries the flexible shutter or ourtain 14 whichis of coarse screen material; that is, it is made up of a series ofconnected chains, as shown in Fig. 4, which are light enough to enablethe curtain or shutter to be raised easily and to roll conveniently uponthe roller 13, but strong enough to resist the force of a bullet and toprevent a sneak thief the top of the window frame, see Fig. 2, and

it has at its lower end a hollow sheath 15 which slides in verticalgrooves 15 in the sides of the window frame, and the shutter is alsowide enough to enter these grooves which are metal lined so as toprevent excessive wear. In the hollow sheath 15 are fastened rods 17which extend horizontally from the central portion of the sheet andproject I through its ends, and these rods are adapted to project intoholes 16 which. are produced at frequent intervals in the backs of thegrooves 15*, and it will be seen that when the rods are thrown into theholes the shutter will be held down and fastened. The inner ends of thefastening rods 17 are pivoted to levers 18 which are fulcrumed centrallyin the sheath l5 and project upward through it, so that their upper endsmay be grasped and pressed together so as to release the fastening rods17. The levers 18 are normally pressed apart by a spring 19 which isarranged between them, and the pressure of the spring forces the rods 17outward,so that they normally engage any set of holes 16 which may beopposite them.

It will be seen that to move the curtain or shutten up or down, it isfirst necessary to press the levers so as to retract the rods 17. Thecurtain or shutter is preferably provided with the usual ring 20, whichis hung in the center of the shutter and by which it may be pulled down.For automatically raising the shutter, the arrangement of weights shownin Fig. 1 is preferably employed, although the spring mechanism shown inFig. 5 may be used if desired.

The roller 13, as shown in Fig. 1, is provided with pulleys 21 on whichare wound cables or cords 22, which hang behind the frame in the sameway that sash weights usually hang, and these cables have, at their freeends, weights 23 sufficiently heavy to unwind the cables, turn thepulleys 21 and roller 13, and raise the shutter 14. It will be seen thatwhen the shutter is pulled down, the cables 22 are wound up, thusraising the weights 23, and when the fastening rods 17 are released theweights drop and raise the shutter. The same effect may be had by theuse of the springs 24, as shown in Fig. 5, as by use of the weights. Ashere shown, springs 24:,

which are the usual coil springs, are coiled around the roller at itsends,one end of each spring being secured to the roller and the other toan adjacent support, and when the shutter is pulled down the springs aretightened, and when the shutter is released the reaction of thesprin gsturns the roller and winds up the shutter. t

Having thus described my invention, I claim as new and desire to secureby Letters Patent The combination with the roller and the wire curtainwound thereon and having a channel strip on its lower end and a springor its stated equivalent against the action of which the curtain isunwound, of the oppositely extending bolts within the said channelstrip, levers l8 pivoted at their lower ends within the middle of thestrip and connected above their pivot to the inner ends of the bolts, aspring pressing the upper exposed
